I dont know if this is normal (ive only had my Galaxy S2 for a few weeks) but scrolling between home screens is very unsmooth for me. I only have 3 home screens, I have the default Clock widget and 4 folders on the first, a music player widget and 8 apps on the second, and a data usage widget + 8 apps on the third. My background is not a live wallpaper but it is one that scrolls over all 3 pages. Ive also noticed several games lag slightly, Sonic 4 Episode 1 for example in general feels slightly sluggish, and if I break an invulnerability crate it will freeze up for a split second, same goes for when a boss first appears. I thought the Galaxy S2 was a phone that could deliver a smooth experience no matter what was thrown at it, is what is happening with mine normal or is something perhaps slowing it down?
